Validity's patented LiveFlex® fingerprint sensor technology provides significant improvement over all other fingerprint sensor technologies by delivering industry-leading FAR/FRR performance with as few as one false accept in one million swipes with a nearly 100% enrollment rate. Validity sensors provide enterprise-grade security by taking a system-based approach extending far beyond simple password replacement. Validity sensors feature SecureMatch™ protecting system credentials by verifying the fingerprint sent to the host processor with the one matched on-chip; one-time passwords (OTP) for securing remote transactions; and RSA public key encryption, AES-256 data encryption, SHA-256 hash algorithm, and SSL cryptographic protocol for protecting the secrecy of fingerprint images, templates and other transmitted data.
With built in touch-based navigation functionality, Validity sensors also greatly enhance smartphone and tablet user functionality. Full 360 degree cursor control is provided as is scrolling, simplifying navigation and selection with today's larger touch-based devices.
The company's Patented LiveFlex technology provides industry-leading fingerprint imaging performance through the use of high-frequency AM-modulated RF signals to penetrate into the skin's inner live layer to scan where the fingerprint is formed, minimizing effects due to dirty, worn, or calloused skin. Additionally, the LiveFlex architecture separates the sensor from the IC, resolving fundamental cost challenges while maintaining excellent imaging quality by moving the fingerprint sensing elements off the silicon die.
LiveFlex sensors enable solutions ranging from invisible, under-glass sensors for smartphones; buttons for handsets and tablets; and the world's thinnest palm-rest designs for Ultrabook® computers.
Validity sensors are constructed using a Chip-on-Flex (COF) architecture where a fingerprint IC (the "chip") is attached to a flexible circuit board (the "flex"). The flex consists of a very thin, low-cost metallized Kapton™ film, in which the metal traces patterned in the film form the sense elements of the fingerprint sensor. These traces are both driven and sensed by the fingerprint IC.
This patented method of separating the sensor element from the IC allows Validity to follow a traditional die-shrink product roadmap while maintaining the highest performance and design flexibility. This is in contrast to competing products where the sensor is the silicon, and therefore the silicon cannot be shrunk without severely degrading FAR/FRR performance, and where novel "invisible" sensor architectures cannot be readily implemented.
